We all do man. Hahaha. You are right in a way though. Thinking lets you adjust timing, tricks, and implement strategies in a fight. I think it is just natural that the "brainier" a guy is the more apt he is to fight more technically and defensively. He knows what lies ahead if he slips and is always calculating. He notices he is getting hit and tries something else. Thinking may not be the most important thing, but you are right about thinking being the key that makes 1 + 1 = 3.
